Mafell KSS 300 MaxiMAX Mitered Miter Saw in the T-MAX

Cut floorboards, parquet, and laminate right where you’re installing them, instead of running back and forth to a stationary crosscut saw for every cut: That’s what the KSS 300 is built for—weighing just 3.0 kg with the rail, it’s the lightest tool in this line. It also handles ceiling panels, wall paneling, doors, and—with the FX 140 flexible rail—recessed joints starting at 13 mm right at the wall. Mafell’s guiding principle behind this: The machine goes to the workpiece, not the workpiece to the machine (manufacturer’s statement).

How it works: Two guide cams press against the workpiece lying on the table; you push the saw across the cut, and the return mechanism automatically pulls it back—40 mm on the crosscut rail, 42 mm free, 300 mm crosscut length. The FLIPPKEIL prevents kickback and folds away for plunge cuts instead of having to be removed.

Buying the Mafell saw at RUWI isn’t a given: We’re manufacturers ourselves—tools for woodworking professionals from Fluorn-Winzeln, 4 kilometers from the Mafell factory in Oberndorf am Neckar. We carry products that we can recommend based on our own experience—including a specialized tool like this one, if it’s exactly what you need for your work.

Here's how to use it

• Cut on site: Cut the flooring, panels, and trim to size right where they’ll be installed—3.0 kg, always on hand.
• Cutting shadow gaps: starting at a 13 mm wall clearance using the FX 140 Flexi-Rail.
• Making miter cuts: −45° to +60°—a marking pointer for every angle, because the pivot point is located at the bottom edge of the rail.
• Reaching tight spaces: the most compact design in the product family, ideal for renovation and existing buildings.

Does this fit in your workshop?

40 mm is the clear cutoff: 45 mm frame wood is a job for the KSS 50 cc, and anything up to 67 mm is for the KSS 60 cc. The KSS 300 doesn’t have the F-rail dual-roll system found on its larger counterparts—its secondary role is as a small handheld circular saw for panels. Batch work at a fixed workshop station is best left to the Erika or a stationary crosscut saw, and the KSS 40 18M bl is the cordless model in the same 40-mm class.
